With an interest only mortgage, your monthly payments cover the interest charged by the lender, while the mortgage balance itself is repaid separately at the end of the mortgage term.
This is different from a repayment mortgage, where each monthly payment gradually reduces the amount owed over time.
Interest only mortgages are commonly linked with buy-to-let mortgages, though residential interest only options are still available for the right borrowers.
Lenders will usually look at factors such as your income, equity position, deposit size, age, and how you plan to repay the balance later on.
Some customers take out an interest only mortgage to reduce their monthly mortgage payments, while others are remortgaging an existing interest only deal that is coming to an end.
There are also lenders offering part and part mortgages, where part of the borrowing stays on interest only while the remaining balance is repaid monthly.
Our Customers Rate us 4.9/5
Interest only mortgages are usually aimed at borrowers with stronger overall affordability, larger deposits or higher levels of equity.
Compared to a standard repayment mortgage, lenders will often apply stricter criteria when assessing a residential interest only application.
Your income will play a big part in what lenders are willing to offer, especially for larger loan amounts.
Some lenders also expect borrowers to have a clear repayment strategy in place from the beginning, such as investments, pension funds, property sale plans, or other assets that could eventually repay the balance.
Residential interest only mortgages can suit a range of circumstances, including employed borrowers, self employed applicants, company directors, and customers with more complex income structures.
Existing mortgage balance, credit history, age, property type, and the amount of equity available can all influence which lenders are available to you.
For customers who do not fully meet interest only criteria, part and part mortgages may also be an option. This allows part of the mortgage to stay on interest only while the remaining balance is repaid monthly.

Many customers looking at interest only mortgages already have existing borrowing in place and want to understand what their options are before their current deal ends.
Depending on your circumstances, it may be possible to remortgage onto a new interest only deal, extend the mortgage term, reduce the balance, or move part of the borrowing onto repayment.
Lenders will usually review your affordability, equity position, income, age, and repayment strategy when assessing your remortgage options.
For some borrowers, downsizing plans, pension income, investments, or property sale plans may form part of the discussion around how the balance will eventually be repaid.
If your current lender will not offer a new interest only deal, there may still be alternative lenders available depending on your circumstances.
Some customers also explore part and part mortgages as a way of reducing the balance gradually while still keeping monthly payments lower than a full repayment mortgage.

As first-time buyers, we had very little knowledge of the mortgage process and found it quite daunting, especially with rising interest rates and uncertainty in the property market. We’re extremely grateful to Dinah and Jo for their support and would highly recommend UK Moneyman to any first-time buyer looking for a professional, knowledgeable and supportive mortgage broker.

As first-time buyers, we had very little knowledge of the mortgage process. We changed properties along the way, and our circumstances made the mortgage process more complex than we initially expected. Dinah and Jo were absolutely brilliant throughout. We would definitely recommend UK Moneyman to anyone looking to set up a mortgage.

Leo and Lizzi were exceptionally helpful. Leo gave us great advise, not just on products available, but on things like bidding on properties, whether we were likely to be approved for more complicated properties etc. Lizzi was very communicative and thorough in processing our application, and after our first sale fell through we didn't hesitate to use UK Moneyman again. Thanks so much to Leo and Lizzi!
